Bugs in content types

Hello.

I mostly use question sets.

When I add a True/False question in the Question Set, if the Show "Check" buttons are checked in the Settings for "Check", "Show solution" and "Retry" section below, everything works fine and a red cross appears.

However, if the Show "Check" buttons are not checked, then the red cross does not appear.

When I examine the classes, the "WRONG" class is not added. Only the "CORRECT" class is added.

we just updated to PHP 7.4 and now I am unable to upload any images into my current H5P programs. I have reduced the size and nothing works.

When i try to upload content that I use on another site i get an error message for all files that containes a presentation with sound files to each slide.

Is there a way to fix this or a work around?

I get this errore message:

(413)

Unable to interpret response.

Please check your error log.
